HEATING AND VENTILATING DRUM SPECIFICATION forming part of Letters Patent No. 701,286, dated June 3, 1902..

Application filed March 31, 1902. Serial No. 100,701. (No model.)

1'0 all whom it may concern.-

Be it known that I, ARTHUR WV. BROOK, a citizen of the United States of America, residing at Alma, in the county of Gratiot and State of Michigan, have invented certain new and useful Improvements in Heating and Ventilating Drums, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in heating-drums, and applies to that class intended to be used in connection with furnaces and stoves through which the products of combustion are to be passed for the purpose of obtaining the benefit by radiation of the heat therefrom, and it may either be applied in the room above the stove or furnace or in the same room, if desired, and the invention is designed as an improvement upon my prior patent, No. 458,013, of August 18, 1891, in which patent the circulation in the upper heating-chamber was sluggish on account of the short distance the air had to travel from the intake to the outlet and the short time it had to become thoroughly heated; and one of the objects of my invention is to overcome this difficulty by carrying the intake-pipe for the upper chamber down through the lower chamber, so that the air will become heated in the lower chamber, thus having an opportunity to give off some of this heat in passing from the lower to the upper chamber, and then be finally reheated again in the upper chamber before being discharged into the room, thereby adding greatly to the heating capacity of the drum, besides obtaining a much more rapid circulation of the air, a further object of the invention being to provide ready access to the interior of the drum for the purpose of cleaning the same.

To this end the invention consists in the peculiar construction, arrangement, and combination of parts, all as more fully hereinafter described, and shown in the accompanying drawings, in whioh-- Figure 1 is a side elevation of my improved heating-drum with the upper and lower sec tions shown as detached; Fig. 2, a vertical central section therethrough; Fig. 3, a vertical central. section through the lower portion of the heating-drum, illustrating a modified construction.

A is the main inlet-flue, by means of which the drum is connected with the smoke-outlet from the stove or furnace.

B and O are the vertical branches thereof, the former forming a direct passage and the other an indirect down-passage.

E is the lower smoke-chamber, into which the indirect passage 0 communicates, and D is the upper smoke-chamber, into which the direct passage communicates.

F is a removable hood forming the top portion of the upper chamber D,and H is the smoke-exit from said chamber, and I is a hotair chamber suspended within the hood F by means of the fines J J, connecting said cham ber with the atmosphere.

K is an air-inlet into the bottom of the hotair chamber and which fits in the flue K when the hood is secured upon the upper chamber,and which flue extends clear through and into proximity with the hopper-shaped bottom of the lower chamber, a detachable section K being sleeved on the lower end of said fine and extending through the bottom of said chamber and preferably carrying a suitable damper arrangement hereinafter more fully described.

L represents three hot-air fiues passing vertically through the lower chamber E, and P represents two smoke-fines leading from the top of the lower chamber into the bottom of the upper chamber. a

Q is a partitioned wall in the lower chamber, reaching down from the top to near the bottom of said chamber, so as to cause the products of combustion to be carrieddown to the bottom of said chamber before they can pass up through the smoke-fines P, and thus thoroughly heat the air-fines. The hoppershaped bottom of the chamber E is provided with a central aperture for the reception of the detachable section K of the central airfiue and a concentric series of openings S, and T is an inclined collar formed with a corresponding series of openings carried by the extension K and adapted to register with the openings S, and V is a downward extension forming a handle for the purpose of opening or closing said openings to regulate the draft, as desired.

W represents legs integral with the lower portion of the drum, and G is a damper in the direct branch B.

In practice it the damper is placed in the position shown in Fig. 2 the products of combustion from the stove are directed through the branch 0 into the lower chamber E and are compelled to pass to the bottom thereof below the partition Q and then upwardly through the flues P into the upper chamber and through the exit-flue into the chimney.

During this passage it will be seen that the hot gases will pass around the pipes K and L in the lower chamber and thoroughly heat the same, thus causing the air to enter the bottom of these pipes and be discharged in a heated condition at the top, that, however, in the pipe or flue K passing onup into the hot-air chamber and simply giving off its heat by radiation in passing from the lower into the upper chamber, during which time it will have acquired sufficient momentum to carry it up through the hot-air chamber and into the room after having again been thoroughly reheated. The gases of combustion in passing into the upper chamber will envelop the hot-air chamber and thoroughly reheat the air therein which may have become cooled in passing from the lower into the upper chamber, after which the hot air is dischargedinto the room through the flues J.

If the damper G is turned in the position shown in dotted lines in Fig. 2, the hot gases from the stove will directly enter into the upper chamber and simply heat the air in the chamberIthereof, and by adjusting the damper into any intermediate position part of the gases may be compelled to pass through the indirect branch into the lower chamber and through that into the upper chamber, while the rest finds its exit directly into the upper chamber, and the amount of hot air may be thus regulated to satisfy the circumstances.

In Fig. 3 I have shown a modified construction, in which the lower ends of the air-flues L project out through the side of the casing, which may be connectedby separate pipes with the outside air, thus bringing constantly fresh air into the room and heating it to a moderate temperature. At the same time the rotating collar or damper T may be turned to open the registering holes whenever the air becomes foul and the foul air drawn from the room into the chamber E and be carried away with the hot gases into the chimney. This ventilation will be especially eifective when the damper G is open for direct draft and the damper G closed. It will further be seen that the removable hood F permits of cleaning out the soot and dirt in the upper chamber and brushing it into the lower chamber through the flues P, and from which the soot is removed by taking out the pipe K a suitable receptacle being placed therebeneath to catch the debris, after which the pipe K may be put back into place and the device is ready for further operation. I may preferably make the lower chamber in sections, as shown, so that it may readily be taken apart at any time should occasion demand.

Having thus fully described my invention,

what I claim is bottom of said flue, a damper in said vertical flue, independent air-fines in said lower chamber, a hot-air chamber in said upper chamber, air inlet and outlet flues for said chamber, said inlet-flue extending down through the bottom of the upper chamber and partially through the lower chamber and a detachable extension projecting through the bottom of the lower chamber, sleeved on said flue, for the purpose described.
